required to gain traction. To turn ESP on again, momen-
tarily depress the ESP OFF switch. This will restore the
normal “ESP On” mode of operation.
NOTE:To improve the vehicle’s traction when driving
with snow chains, or starting off in deep snow, sand, or
gravel, it may be desirable to switch to the “Partial Off” mode by pressing the ESP OFF switch. Once the situation
requiring ESP to be switched to the “Partial Off” mode is
overcome, turn ESP back on by momentarily depressing
the ESP OFF switch. This may be done while the vehicle
is in motion.
ESP Off (4H Range Only)
This mode is intended for off-highway or off-road use
when ESP stability features could inhibit vehicle maneu-
verability due to trail conditions. This mode is entered by
depressing and holding the ESP OFF switch for five
seconds when the vehicle is stopped and the engine is
running. In this mode, all ESP and TCS stability features
are turned off except for the “limited slip” feature de-
scribed in the TCS section. After five seconds, a chime
will sound, the ESP/TCS Indicator Light will illuminate,
and the “ESP OFF
message will appear in the odometer.
Refer to “Compass and Mini-Trip Computer — If
Equipped” in Section 4 of this manual. To turn ESP on

When the CAL symbol is no longer displayed, the
compass is calibrated and should display correct head-
ings. Verify proper calibration by checking North (N),
South (S), East (E), and West (W). If the compass does not
appear accurate, repeat the calibration procedure in an-
other area.
Compass Variance (VAR)
Variance is the difference between magnetic North and
geographic North. For proper compass function, the
correct variance zone must be set.
Setting the Compass Variance
Refer to the variance map for the correct compass vari-
ance zone. To check the variance zone, the ignition must
be ON. Press and hold the left button (located on the
instrument cluster) for approximately 10 seconds to enter
the variance mode and release the button when the VAR
symbol appears. The current variance value will also be
displayed. To change the zone, press the left button onceto increment the zone. The default is Zone 8. After Zone
15, the values will wrap around to Zone 1. When the
correct zone is displayed (per the Compass Variance
Zone Map) for the zone that the vehicle is located in, wait
for about five seconds, then the trip computer will store
the variance value in memory and the compass will
resume normal operation.
NOTE:
The U.S./Metric display will change from En-
glish to Metric or Metric to English before the VAR
symbol appears, however, it will revert back to its
original setting after programming the compass func-
tions.
